Pulling power decreases sharply with every subsequent millimeter of distance. Keep in mind that even the smallest gap (e.g., contamination, paint, veneer) noticeably diminishes the holding power. Magnets operate optimally at the point of direct contact; air break weakens the power. Analyze how quickly the parameters fall, when the magnet does not adhere tightly to the steel surface. When planning the mounting, eliminate unnecessary gaps.

This section presents the estimated holding capacity necessary to initiate the downward movement of the magnet downwards along a vertical steel plate (considering standard friction coefficient). This value is a function of the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MPL 20x3x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.70 kg / 1.54 pounds 699.0 g / 6.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.47 kg / 1.03 pounds 466.0 g / 4.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.23 kg / 0.51 pounds 233.0 g / 2.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.17 kg / 2.57 pounds 1165.0 g / 11.4 N

When placing a holder on a upright plane (e.g., a car body), it will only hold just approx. 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient cause that products move down faster than they detach. Planning a hanger? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slip down under a much lighter load. Using a rubber pad can effectively increase the grip.

A thin metal plate is unable to conduct the full magnetic flux, which squanders power of the magnet. If you mount a strong magnet to a thin surface, the magnetism will pass right through and the holding will be smaller. To achieve the maximum of this magnet's potential, you require a sufficiently solid piece of steel. The saturation effect causes that on thin elements (e.g., appliance housings), the holder shows lower pull force. We recommend selecting the steel dimension from these parameters.

Ordinary NdFeB products lose power above the temperature limit. Protect against heat – high temperature can permanently damage this magnet. As the temperature rises, the neodymium's force momentarily drops. Refrain from using this product close to ovens higher than its working range. Exceeding the critical threshold will cause destruction of magnetic properties.

*Important note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) are more susceptible to demagnetization at lower temperatures than long magnets. Warning indicator in the table points to permanent field degradation for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet setup. Such a system of magnet-to-magnet generates a stronger field and a wider radius of operation. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the impact force is extreme. The levitation is slightly lower than the attraction, but still impressive.
*Field value for N-N configuration drops to ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Attention: Calculations demonstrate sliding force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a real danger to electronics and medical implants. These neodymiums generate a field that destroys function of sensitive medical devices. Be aware: the unseen radiation passes through tissues and plastic. Special caution must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are delicate – a collision with steel can result in shattering. Watch the impact speed – a neodymium left loose speeds with massive force. Striking energy can cause material chips or painful pinches to skin. Be sure to control the product during mounting so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear safety glasses when handling with large magnets.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Shear force

*Warning: On a vertical surface, the magnet holds just approx. 20-30% of its max power.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) severely limits the holding force.

3. Temperature resistance

*For N38 grade, the max working temp is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.32

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The P_c (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher P_c value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

Model MPL 20x3x2 / N38 features a flat shape and professional pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 2.33 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is sliding the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. Watch your fingers! Magnets with a force of 2.33 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 20x3x2 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. They work great as invisible mounts under tiles, wood, or glass. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. In practice, this means that this magnet has the greatest attraction force on its main planes (20x3 mm), which is ideal for flat mounting. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

The presented product is a neodymium magnet with precisely defined parameters: 20 mm (length), 3 mm (width), and 2 mm (thickness). It is a magnetic block with dimensions 20x3x2 mm and a self-weight of 0.9 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Advantages

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They do not lose strength, even over around ten years – the drop in power is only ~1% (theoretically),
They feature excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
In other words, due to the metallic surface of nickel, the element gains a professional look,
The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to freedom in forming and the capacity to adapt to individual projects,
Huge importance in future technologies – they are used in mass storage devices, electric drive systems, diagnostic systems, also multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems

Disadvantages

Drawbacks and weaknesses of neodymium magnets: tips and applications.

At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We recommend a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
Health risk to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small elements of these devices can be problematic in diagnostics medical after entering the body.
With large orders the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum holding power of the magnet – what contributes to it?

Holding force of 2.33 kg is a measurement result performed under specific, ideal conditions:

on a base made of structural steel, optimally conducting the magnetic flux
with a cross-section of at least 10 mm
with a plane perfectly flat
with direct contact (no impurities)
for force applied at a right angle (pull-off, not shear)
in neutral thermal conditions

Magnet lifting force in use – key factors

Effective lifting capacity is affected by working environment parameters, including (from priority):

Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Load vector – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
Material type – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was determined with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet and the plate lowers the holding force.

Warnings

Combustion hazard

Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

Swallowing risk

Product intended for adults. Small elements pose a choking risk, leading to serious injuries. Keep out of reach of children and animals.

Do not overheat magnets

Avoid heat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).

Safe distance

Do not bring magnets near a wallet, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.

Pinching danger

Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!

Pacemakers

Patients with a ICD have to maintain an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.

Safe operation

Handle with care. Rare earth magnets attract from a distance and snap with huge force, often faster than you can react.

Magnets are brittle

Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Magnetic interference

A powerful magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets close to a smartphone to avoid damaging the sensors.

Nickel coating and allergies

Certain individuals experience a contact allergy to Ni, which is the common plating for neodymium magnets. Frequent touching might lead to dermatitis. We suggest wear protective gloves.
